I have this code here below. It basically rotates a box in 3D. I know I can rotate the camera using camorbit but I actually want to rotate the object, not the camera around it. So the strategy is to create an element in so(3) and take the exponential map to SO(3) as the element is varied continuously over time.
yo = unique([-1 -1 -1; perms([1 1 -1]); perms([1 -1 -1]); 1 1 1], 'rows');
yo2 = delaunay(yo(:,1), yo(:,2), yo(:,3));
r(:,:,i) = vrrotmat2vec(expm(seedMat*t(i)));
axis([ -2 2 -2 2 -2 2])
My question is why is this animation jerky? Is there something that I can do to fix it?
EDIT: Changing the last part as follows, made the buggy/jerky behavior go away, but resulted in an entirely new rotation behavior. So i am not sure if it is the correct approach or not. Can someone comment?
